Outstanding reply! You are awarded the winner of my trivia question!
We will set aside the problem of the Sima Violet to another day.
Imagine, if you can, a one off special built almost 50 years ago (now 90) and having the following features;
1. A 4 cylinder stepped bore, 8 piston, vertically opposed, supercharged, 2-stroke engine with 2 crankshafts one of which runs through the skirt of the top pistons.
2. An engine which runs to 8000rpm.
3. Twin plugs per cylinder producing 64000 sparks per minute (from 8 coils) at 8000rpm.
4. Front wheel drive with inboard brakes.
5. Four wheel independent suspension.
6. A space frame chassis of small diameter tubes, much of it triangulated.
7. An 1100cc 85+ BHP motor.
8. Virtually the whole car built in Australia.
Any one of these features would have been remarkable and distinctive in 1929 when the car itself was built, or in the early 1930’s when the present engine was inserted. In combination the assemblage of features makes for one of the most amazing cars the world has seen. That it was constructed by a small group of enthusiasts rather than a large and experienced factory makes it all the more remarkable.

The car is the ear-splitting Chamberlain Special and its builders are Alan (Bob) and Howard (Bill) Chamberlain (with a little help from their friends). Bob built the original car while Bill built the 8-cylinder, 2-stroke engine.
